The steps for a project in County Antrim
Survey
We size the unit to the room and agree indoor and outdoor positions and the pipe route.
Mount the units
Indoor unit on a mounting plate, outdoor unit on brackets or a frame with anti-vibration mounts.
Pipe and wire
Pipework, interconnecting cable and condensate are run and made off neatly. In County Antrim we agree timings around your opening hours.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
Before you book in County Antrim
Outdoor unit position
Outdoor units need air flow and access, and should be away from neighbours' windows to keep noise down.
Conservation areas
Historic streets and listed buildings in and around County Antrim are more likely to need planning permission for outdoor units on visible elevations. We check with the council's planning service before work is booked.
One outdoor unit, many rooms
Multi-splits save wall space but share a single compressor. For server rooms or critical spaces we recommend dedicated systems.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Who we work with in County Antrim
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
In Northern Ireland, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under EU F-gas rules that apply in Northern Ireland, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
